Abstract:
This experiment began in 1958 at a site that has been in arable crops for more than 100 years. The climate of the site is cool temperate, with mean annual temperature of 9.1 deg. C, and Mean annual rainfall of 598mm. The experiment consists of Cereals only with either inorganic fertilizers only (2 types) or inorganic fertilizers (2 types) plus straw incorporation, in a block design, replicated 4 ... times.

The soil at the site is described as an Orthic luvisol (FAO) [derived from loess].

Details of soil sampling method: Sampled by auger (30cm x 3cm), 10 cores per plot (total plot area 7.0 x 3.0m; sampled area about 5 x 2.5m). Sampling is randomized. The ploughing depth (and sampling depth) was increased from 15 to 20cm in 1969 and from 20 to 30cm in 1986 (due to available technical equipment for soil tillage).

Nearest meteorological station to the site: Klein-Altendorf which is .4 km from the site at coordinates 7deg.00min. East, 30deg.36min. North Meteorological data is available from both a manual and an automatic station.
